GEOLOGY

Detailed explanation-1: -In saturated loose or soft granular soils, liquefaction occurs when the shear strains induced due to seismic shaking cause transient pore water pressures to increase in the soil mass.

Detailed explanation-2: -Liquefaction takes place when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking.

Detailed explanation-3: -Liquefaction occurs when an earthquake’s violent shaking suddenly turns loose, soft soil into liquid mud.

Detailed explanation-4: -Soil Liquefaction Due to Earthquakes Earthquake motion can turn loosely packed, water-saturated soil to liquid-"liquefaction.” Liquefied soil loses its density and ultimately the ability to support roads, buried pipes, and, of course, houses.

Detailed explanation-5: -Liquefaction is the destabilization of sand or soil when groundwater (water underground) is forced out from between grains during the shaking of a moderate or strong earthquake. If liquefaction occurs under a building, it may start to lean, tip over, or sink several feet.
